The so-called Strecker reaction, in which a halogenated organic compound and a sulfite are reacted, is extremely useful for introducing a sulfone group. However, in this method, a dehydrohalogenation reaction occurs between the halogenated organic compound as the starting material and the organic sulfonic acid produced, resulting in the production of a small amount or large amount of by-products, an increase in the number of purification steps, and the production of by-products. This caused problems such as contamination with products and wastewater treatment, making it unsuitable for industrial production.

見に基づき本発明を完成するに至つた。
As a result of intensive research to overcome the above-mentioned drawbacks of conventional methods, the present inventors discovered that when sulfonating a halogenated organic compound having an amino group, an excessive amount of bisulfite is present in the reaction system. This suppresses the production of side reactants, which are inactive ingredients, and facilitates the separation and production of reaction products, making it possible to produce organic sulfonic acids at low cost and under mild conditions, and facilitating wastewater treatment. Based on this finding, we have completed the present invention.
